One of my old friends used to cut. She said that it helped her release her mental pain, but I only saw evidence of that increasing as well.
I've never cut myself intentionally, so I don't quite understand. I was wondering if it's anything like the rush of being hit/whipped or anything like that during sex play.
For those of you who don't mind links, this is an interesting one to do with the topic.
http://kidshealth.org/teen/your_mind...h/cutting.html It gives a basic history and some possible reasons, and also gives advice on how to begin to stop cutting, if it's become a habit.
